针对春风油田浅层稠油油藏特点,研发了一种热采井RCD-1耐温长效堵剂。依据试验区油藏地质条件,筛选出了RCD-1耐温长效堵剂配方,该配方由10~12%的主剂、4~5%的助剂、0.5%的稳定剂及余量为水。室内实验表明,RCD-1耐温长效堵剂具有较高的强度和封堵性能。RCD-1耐温长效堵剂现场试验4井次,应用效果表明,平均单井日增油10.9t/d,含水下降了16.6%,单井增油860t,累计增油3440t。
In view of the characteristics of shallow heavy oil reservoirs in Chunfeng Oilfield, a long-term thermal blockage agent RCD-1 was developed. Based on the reservoir geological conditions in the experimental area, the RCD-1 temperature-resistant long-acting plugging agent formulation was screened. The formulation consisted of 10 to 12% of main agent, 4 to 5% of auxiliary agent, 0.5% of stabilizer and the balance of water. Laboratory experiments show that RCD-1 temperature-resistant plugging agent has high strength and sealing performance. RCD-1 temperature-resistant and long-acting plugging agent field test 4 times, the application results show that the average single well daily oil 10.9t / d, water decreased by 16.6%, single well oil 860t, cumulative oil 3440t.
